hidden lock for chests having hinged lids, the

lock being` operatedwithout a lrey by ineanso't a secreted button.

A third important object of the invent-ion is to provide an improved form of lock for chests having` hinged lidsvvherein the hinges themselves will, when the lid is in fully closed position, :torni the main locking means, the

leaves of the hinges being secured. against swinging movement upon the lid being placed in its fully closed position.

Vith the above and yother objects in view as will be hereinafter apparent, the invention consists in generalofy certain novel details of co struction and combinations of parts hereinafter fully described7 illustrated in' the accompanying drawings and specifically claimed. ,e

In the accompanying drawings like characters of reference indicate like' parts in the several views, and:

Figure 1 is a plan view of the chest with the improved lock, thel lid being shown in ully opened position.

Figure 2 is a side elevation, partly in section and Vpartly broken away, of one'of the hinges in its fully opened position. e y

Y Figure 8 is a. view similar to Figure 2 but showing the hinge closed and ready for Inovement to locking position.

Figure fl is a view similar toFigure Shut showing thehinge in locking` position.

Figure 5 is a longitudinal vertical section through the lid and housing thereon.V

Figure 6` is a vertical transverse section through thelid andV housing.

AFigure 7 7 7 ot Figure 1 with the lid closed.`

Figure 8 is a. sec-tion on the line 8MS of Figure 7 Figure 9 is an enlarged detail section on the line 9 9 of Figure 1 with the lid closed.`

illustra-ted there is disclosed a chest having the usual side walls 10`v rear wall 11, front wall 12, and cover. 13. Extending along the top of each side wall 10 is a plate .14 which is preferably seated in a. ysuitable channel is an enlarged section on the lineV cut into the top of the wall 1`so that the up-` per surface oli' the plate lll is liush with the top ont said wall. This plate is secured in` position by suitable screws and adjacent the front end of the plate is a key hole slot ar` ranged with the larger or entry end of the key hole toward the rear. Also the plate 14 has a centrally disposed pin holeV 16.

The lid is connected to the body of the chest by a pair of hinges each of whichhas a shorter leal 1'? and a longer leaf 18. The shorter leaIn of each hinge is slidably mounted on the rear portion of a respective plate 14, the mounting' being effected in the following manner. In the leaf 17 is formed a pair of longitudinal slots 19 of T-shape in crossv section and in each slot is litt/ed a T-shaped guide block 2O secured to the plate lll by screws 21.V sliding moveinent'on the plate 14. The long leaf 18 is screwed .firmly to the underside of the lid 18. Nearthe tree end ot each long leafjisiined a headed piu QZthepin being` positioned at such point that, with the hinges slid as tar back as thevwill go and the leaves folded 'together (see Figure 3), thefpin will passthrough the large end ot the keyhole slot. The head on this pin is of greater di-` ameter than the width of the smaller end of said slot .so that, with the hinge slid forward. as in Figure 4, the leaves cannot be unfolded and the lid cannot be raised. Preferably the hinfge is countersunk into the lid as shownVv lever pivoted to the lid through a fulcrum bloclr or bearing` 26. ffl. spring 27, beneath the inner end oit this lever. urges the pin into-protracted position so that whilethe pin mayretract to permit closing oft-he leaves as in Figf yure 3.as soon Vas the pin alines with the pin hole 16 it will be forced into that` hole and Y l the hinge cannot be slid on the plate 14. untilv In the embodiment ot the invention herein the pin ris again withdrawn. p

@in top oit. the lid 18- isran ornamental housing 28 across which runs a shelf 29 and this housing covers the levers and pinsy and conceals them both from being tampered with and from view. Connecting the inner ends of Thus the leall 17 has limitedy cure the hinge against sliding movement on f the plate.

the levers is a presser bar 30 the central portion of which extends over the shelf 29'and is supported thereabove by springs 3l; Projecty ing from the center of this bar through the iop of the housing is a presser-buttonBQ 'whic-h has its upper end carved to form part of and be concealed by the ornament 83. means a person, knowing the secret of the lock, can open the chest by pushing down on the button 32, which frees the pins from the holes 16, and then sliding the lid back to allow the pins 22 to pass out of the large end of the slots l5 as the front of the lid is raised.

In order to aid in keeping the back ofthe. lid from being sprung up there is mounted on the Wall ll a pair of eye plates 34 and in recesses 35 in the underside of the top pin members 36 which, when the lid is closed, as in Figure 9, will engage in said eye plates upon the lid Abeing slid forwardly, the lid' in saidv figure being shown as closed but not slid forwardly to its'final position for closing the chest. Y

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.`

It is obvious that minor changes may be made in the formand construction of the invention without departing from the materialy spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

l. In a device of the kind described,a plate having a key hole slot at one end, a hinge having a short leaf slidably mounted on said plate and a long leaf foldable to bring its free end `over the key hole slot, and a headed pin carried by said long leaf and engageable in said key hole slot to enter the wide endy and slide into the narrow end.

2. In a device of the kind described,.a plate having a keyv hole slot at one end, a hinge' having a short leaf slidably mounted on said said key7 hole slot to enter the wide end and slide into the narrow end, and means to se- 3. In a device of the kind described, a plate having a key. hole slotat one end, a hinge having a short leaf slidably mounted on said plate and a long leaf foldable to bring its free end over the key hole slot, a headed pin carried by said Vlong leaf and engageable in said key hole slot to enter the wide end and slide into the narrow end, said plate also having a pin hol'e opening therein, and a spring pressed retractile pin carried by said long leaf and positioned to enter said By this f pin hole upon the headed pin being moved into the narrow end of the keyhole slot;`
